Description

Technical Field

[0001] This invention relates to the field of hydrochloric acid storage tank technology, specifically to a hydrochloric acid storage tank with an anti-sway mechanism. Background Technology

[0002] Hydrochloric acid storage tanks are specialized containers for holding highly corrosive liquids such as hydrochloric acid and sulfuric acid, and are mainly made of plastic or fiberglass. Plastic storage tanks are mostly made of polypropylene (PP) and are formed in one piece through rotational molding, suitable for short-term storage (1-2 years) and small-sized packaging; fiberglass storage tanks have their stability verified through resin selection and coating experiments, and have corrosion resistance of more than 30 years, making them the mainstream choice in chemical production.

[0003] The existing hydrochloric acid storage tanks have the following problems: 1. The external facilities of the hydrochloric acid storage tank are reinforced to prevent shaking when hydrochloric acid is poured in, but this indirectly restricts the movement of the hydrochloric acid storage tank and makes transportation inconvenient; 2. The pouring of hydrochloric acid will create a height difference. After the hydrochloric acid is sprayed out of the pipeline, it will impact the liquid surface or the bottom of the tank at a certain speed, forming a "liquid column impact". At the same time, the wave-like surge of the hydrochloric acid liquid surface will also impact the inner wall of the tank, thus causing shaking. Summary of the Invention

[0004] The present invention provides a hydrochloric acid storage tank with an anti-sway mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hydrochloric acid storage tank with an anti-sway mechanism, comprising a saddle support for supporting the hydrochloric acid storage tank, wherein the hydrochloric acid tank is disposed inside the saddle support; A fixed rail is provided at the center of the bottom of the saddle support. A servo motor is connected to the outer end face of the fixed rail by fasteners. The output end of the servo motor is connected to a lead screw by a coupling. The two ends of the lead screw are connected to the two ends of the fixed rail by bearings; A feeding mechanism for regulating and controlling the flow rate of hydrochloric acid is provided on the fixed rail. An anti-sloshing mechanism is provided inside the hydrochloric acid tank to prevent hydrochloric acid solution from entering and causing the hydrochloric acid storage tank to shake. The hydrochloric acid tank is equipped with a vertical anti-sway plate welded inside, and the outer side of the vertical anti-sway plate has a vertical groove. The anti-sway plate cuts the liquid flow and blocks the propagation of waves. At the same time, the vertical groove allows the liquid to flow slowly, avoiding the formation of pressure difference that could cause the plate to deform.

[0006] Preferably, a first floating plate is slidably fitted inside the vertical groove, and a prompting rod is welded to the top of the first floating plate. The prompting rod passes through the top of the hydrochloric acid tank and extends to the outside. The hydrochloric acid solution moves the first floating plate upwards, causing the indicator rod to protrude upwards from the top of the hydrochloric acid tank.

[0007] Preferably, the feeding mechanism includes an internally threaded slide plate, which is threadedly connected to the outside of the lead screw. A first feeding pipe is welded and installed inside the internally threaded slide plate, wherein the first feeding pipe is connected to an external hydrochloric acid pipeline, and inclined sleeves are symmetrically fitted on both sides of the first feeding pipe. A sealing gasket is installed on the outside of the No. 1 feed pipe.

[0008] Preferably, a pipe connector is welded to the end of the inclined sleeve away from the first feed pipe, an arc-shaped pipe is welded to the top of the pipe connector, a limiting plate is welded to the end of the arc-shaped pipe away from the pipe connector, and a folded pipe is welded to the outside of the limiting plate. The portion of the folding tube connected to the limiting plate has folding capability.

[0009] Preferably, a second feed pipe is welded and installed inside the hydrochloric acid tank, the inside of the second feed pipe is fitted with the folded pipe, and a second floating plate is inserted into the bottom of the second feed pipe; The second floating plate is raised and extended into the second feed pipe by the injection of hydrochloric acid solution.

[0010] Preferably, a top insertion rod is welded to the top of the second floating plate, the top insertion rod is inserted through the top of the second feed pipe and extends to its outside, and a sealing plate is connected to the top of the top insertion rod through a triangular plate; The sealing plate is used to seal the outlet of the No. 2 feed pipe, and an external connecting strip is welded to the outside of the sealing plate.

[0011] Preferably, the anti-sway mechanism includes a sleeve channel, which is welded to the bottom of the inner cavity of the hydrochloric acid tank, and a top plate is welded to the top of the sleeve channel, wherein the top plate is used for guiding and limiting the No. 1 feed pipe. The outer side of the casing channel is welded with guardrail No. 1 and guardrail No. 2, respectively, and the thickness of guardrail No. 1 is greater than the thickness of guardrail No. 2.

[0012] Preferably, an anti-sway component is provided at the end of the casing channel away from the top plate. The anti-sway component includes an inner pipe, which is welded to the bottom of the inner cavity of the hydrochloric acid tank, and a square hole is provided on the outer side of the inner pipe. The square orifice is used to increase the flow of hydrochloric acid.

[0013] Preferably, a liquid outlet head is welded and installed at the end of the inner pipe away from the casing channel. A discharge hole is opened on the outer side of the liquid outlet head. A protective frame is welded and installed inside the liquid outlet head. A flow baffle is slidably fitted inside the protective frame. The flow baffle is tough and is used to seal the square hole.

[0014] Preferably, a telescopic insert is welded to the end of the flow baffle away from the protective frame, and a connecting rod plate is welded to the end of the telescopic insert away from the flow baffle. The connecting rod plate is slidably adapted to the inside of the inner pipe and is squeezed and adapted to the first feed pipe.

[0015] Preferably, a straight rod is welded to the outer side of the connecting rod plate, and a semi-circular sleeve is welded to the end of the straight rod away from the connecting rod plate. The inner wall of the semi-circular sleeve is in contact with the liquid outlet head, and elastic telescopic rods are welded to both the upper and lower sides of the semi-circular sleeve. The elastic telescopic rods are welded and installed on the outer side of the inner pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By extending the outlet of the filling pipe to the bottom of the storage tank and using a curved pipe and a multi-hole nozzle, the hydrochloric acid flows horizontally along the bottom of the tank, rather than vertically impacting the liquid surface (vertical impact will create violent surging and waves). This avoids the hydrochloric acid solution from surging and impacting the inner wall of the storage tank, thus indirectly causing shaking. At the same time, it avoids filling from a high drop, reducing the impact force caused by the drop.

[0017] 2. A warning bar, welded to the top of the No. 1 floating plate, extends outward from the top of the hydrochloric acid tank to provide operators with guidance for the next operational step. Additionally, the vertical anti-sway plate cuts the liquid flow, blocks wave propagation, and allows the liquid to flow slowly through the vertical channel, preventing pressure differentials from causing plate deformation.

[0018] 3. A portion of the hydrochloric acid inside the No. 1 inlet pipe will sequentially pass through the inclined sleeve, connector, arc-shaped pipe, and folded pipe into the No. 2 inlet pipe, and finally be discharged into the hydrochloric acid tank. This allows the liquid in the tank to absorb the impact force of the newly poured hydrochloric acid (the new liquid mixes with the existing liquid in the tank first, rather than directly impacting the tank wall). Even with increased flow rate, the fluctuation amplitude of the liquid level is much smaller than when the liquid level is low, similar to the effect of "pouring water from a full cup is more stable than pouring water from an empty cup." At the same time, it improves the overall filling efficiency and shortens the operation time.

[0019] 4. The flexible baffle plate will be drawn into the protective frame, while the hydrochloric acid solution inside the inner pipe will be discharged outward from the square hole. This allows for high-flow bottom filling after the liquid level is half full, which can shorten the total time by 40% and eliminate concerns about instability caused by high flow rate, thus balancing efficiency and safety.

[0032] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 11 The present invention provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a saddle support 1 for supporting the hydrochloric acid storage tank, and the hydrochloric acid tank 2 is installed inside the saddle support 1. When saddle supports 1 are installed, there are usually two sets, which evenly support the hydrochloric acid tank 2. A fixed rail 3 is provided at the center of the bottom of the saddle support 1. A servo motor 4 is connected to the outer end face of the fixed rail 3 by fasteners, wherein the fasteners are bolts. The servo motor 4 is installed on the outside of the fixed rail 3 by bolts. The output end of the servo motor 4 is connected to a lead screw 5 through a coupling. The two ends of the lead screw 5 are connected to the two ends of the fixed rail 3 by bearings; The feed mechanism 6 is used to regulate and control the flow rate of hydrochloric acid entering the feed system. The feed mechanism 6 is mounted on the fixed rail 3. An anti-sloshing mechanism 7 is installed inside the hydrochloric acid tank 2 to prevent hydrochloric acid solution from entering and causing the hydrochloric acid storage tank to shake.

[0034] The hydrochloric acid tank 2 has a vertical anti-sway plate 21 welded inside, and a vertical groove 22 is opened on the outside of the vertical anti-sway plate 21. The anti-sway plate cuts the liquid flow and blocks the propagation of waves. At the same time, the vertical groove 22 allows the liquid to flow slowly, avoiding the formation of pressure difference that could cause the plate to deform. The vertical groove 22 is internally fitted with a first floating plate 23. A warning rod 24 is welded to the top of the first floating plate 23, passing through the top of the hydrochloric acid tank 2 and extending outwards. As the hydrochloric acid solution accumulates inside the tank 2, when the solution reaches half its height, it provides buoyancy to the first floating plate 23, causing it to move upwards along the vertical groove 22. Simultaneously, the warning rod 24 welded to the top of the first floating plate 23 extends outwards from the top of the tank 2, providing the operator with guidance for the next step. Additionally, the vertical anti-sway plate 21 cuts the liquid flow and blocks wave propagation, while the vertical groove 22 allows the liquid to flow slowly, preventing pressure differences that could cause plate deformation.

[0035] The hydrochloric acid solution moves upward along with the first floating plate 23, causing the indicator rod 24 to pass through the top of the hydrochloric acid tank 2.

[0036] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the feeding mechanism 6 includes an internally threaded slide plate 61, which is threadedly connected to the outside of the lead screw 5. A first feed pipe 62 is welded and installed inside the internally threaded slide plate 61. The first feed pipe 62 is connected to the external hydrochloric acid pipeline. Slanted sleeves 63 are symmetrically fitted on both sides of the first feed pipe 62. By starting the servo motor 4, the lead screw 5, which is connected to its output end through a coupling, will rotate in the forward direction. The internally threaded slide plate 61, which is threaded to the outside of the lead screw 5, will carry the first feed pipe 62 and move towards the hydrochloric acid tank 2. The inlet of the first feed pipe 62 is connected to the external hydrochloric acid channel, and the other end of the first feed pipe 62 will be inserted into the hydrochloric acid tank 2. The other feed pipe 62 is made of PTFE material and is tough. Then the feed pipe 62 will be inserted into the hydrochloric acid tank 2 and the casing channel 71 in sequence. The outside of the feed pipe 62 is welded with a sealing gasket, which prevents hydrochloric acid from overflowing when the feed pipe 62 is inserted into the hydrochloric acid tank 2 and hydrochloric acid is poured in.

[0037] A sealing gasket is provided on the outside of the No. 1 feed pipe 62; A connector 64 is welded to the end of the inclined sleeve 63 away from the first feed pipe 62. An arc-shaped pipe 65 is welded to the top of the connector 64. A limit plate 66 is welded to the end of the arc-shaped pipe 65 away from the connector 64. A folded pipe 67 is welded to the outside of the limit plate 66. When the indicator rod 24 extends upward from the hydrochloric acid tank 2, the servo motor 4 is restarted. The start and stop of the servo motor 4 are divided into two stages. In the first stage, the folded pipe 67 is inserted into the second feed pipe 81, but the folded pipe 67 is not folded. At the same time, the hydrochloric acid flows out from the outlet 99. In the second stage, the first feed pipe 62 is inserted deeper into the inner pipe 91, and the folded pipe 67 is squeezed and compressed.

[0038] The part of the folding tube 67 that is connected to the limiting plate 66 has folding capability.

[0039] The inside of the hydrochloric acid tank 2 is welded with a second feed pipe 81. The inside of the second feed pipe 81 is fitted with the folded pipe 67. The bottom of the second feed pipe 81 is connected to a second floating plate 82. By injecting hydrochloric acid solution, the second floating plate 82 is raised and extends into the interior of the second feed pipe 81; The top of the second floating plate 82 is welded to a top insertion rod 83. The top insertion rod 83 passes through the top of the second feed pipe 81 and extends to its outside. The top of the top insertion rod 83 is connected to a sealing plate 84 through a triangular plate. The sealing plate 84 is used to seal the outlet of the No. 2 feed pipe 81, and an external connecting strip 85 is welded to the outside of the sealing plate 84. Furthermore, the second stage of the servo motor 4's start and stop coincides with the point when the hydrochloric acid solution accumulates to half the height of the hydrochloric acid tank 2. At this time, the hydrochloric acid solution causes the second floating plate 82 to move upwards, and the top insertion rod 83 connected to the top of the second floating plate 82 moves upwards along with the sealing plate 84 connected to it via a triangular plate. The sealing plate 84 initially seals the outlet of the second feed pipe 81. As the sealing plate 84 moves upwards, some of the hydrochloric acid inside the first feed pipe 62 enters the second feed pipe 81 sequentially through the inclined sleeve 63, the connecting pipe 64, the arc-shaped pipe 65, and the folded pipe 67, and is finally discharged into the hydrochloric acid tank 2. This allows the liquid in the tank to absorb the impact of the newly poured hydrochloric acid, mixing the new liquid with the existing liquid in the tank first, rather than directly impacting the tank wall. Even with increased flow, the fluctuation amplitude of the liquid level is much smaller than that at low liquid levels, similar to the effect of "pouring water from a full cup is more stable than pouring water from an empty cup." At the same time, it improves the overall filling efficiency and shortens the operation time.

[0040] like Figure 9 , Figure 10 and Figure 11As shown, the anti-sway mechanism 7 includes a casing channel 71, which is welded to the bottom of the inner cavity of the hydrochloric acid tank 2. A top plate 72 is welded to the top of the casing channel 71, wherein the top plate 72 is used for guiding and limiting the No. 1 feed pipe 62. The outer side of the casing channel 71 is welded with guardrail No. 1 73 and guardrail No. 2 74, respectively, and the thickness of guardrail No. 1 73 is greater than the thickness of guardrail No. 2 74.

[0041] An anti-sway component 75 is provided at the end of the casing channel 71 away from the top plate 72. The anti-sway component 75 includes an inner pipe 91, which is welded to the bottom of the inner cavity of the hydrochloric acid tank 2. A square hole 92 is provided on the outer side of the inner pipe 91. The square orifice 92 is used to increase the capacity for handling hydrochloric acid inflow; An outlet head 98 is welded and installed at the end of the inner pipe 91 away from the casing channel 71. An outlet hole 99 is opened on the outside of the outlet head 98. A protective frame 93 is welded and installed inside the outlet head 98. A flow baffle 94 is slidably fitted inside the protective frame 93. The flow baffle 94 is tough and is used to block the square hole 92. A telescopic insert 95 is welded to the end of the baffle plate 94 away from the protective frame 93. A connecting rod plate 96 is welded to the end of the telescopic insert 95 away from the baffle plate 94. The connecting rod plate 96 slides inside the inner pipe 91 and is squeezed into the first feed pipe 62. The first feed pipe 62 goes deeper into the inner pipe 91 and squeezes the connecting rod plate 96 a second time. At this time, the telescopic insert 95, which is in a contracted state, squeezes the baffle plate 94, causing the tough baffle plate 94 to be housed in the protective frame 93. At the same time, the hydrochloric acid solution inside the inner pipe 91 is discharged outward from the square hole 92. This structure can realize the operation of large-flow bottom filling after the liquid level is half full. Compared with the low-flow filling mode throughout, the total filling time can be shortened by 40%. At the same time, this design effectively avoids the instability problem caused by high-flow filling and takes into account the efficiency and safety of filling operation.

[0042] A straight rod 97 is welded to the outer side of the connecting rod plate 96. A semi-circular sleeve 90 is welded to the end of the straight rod 97 away from the connecting rod plate 96. The inner wall of the semi-circular sleeve 90 fits against the liquid outlet head 98, and elastic telescopic rods 901 are welded to both the upper and lower sides of the semi-circular sleeve 90. The elastic telescopic rods 901 are welded and installed on the outer side of the inner pipe 91. The first feed pipe 62 is blocked by the limiting plate 72 and then bends forward along the casing channel 71. At the same time, the first guardrail 73 and the second guardrail 74 welded to the casing channel 71 respectively limit the movement of the first feed pipe 62. The purpose of the first guardrail 73 being wider than the second guardrail 74 is that, because the first guardrail 73 is arc-shaped, it prevents the first feed pipe 62 from extending outward from the hollow space between the two first guardrails 73. Finally, the first feed pipe 62 enters the inner pipe 91 and squeezes the connecting rod plate 96 inward. The straight rod 97, connected to the other side of the connecting rod plate 96, passes through the discharge hole 99 outside the liquid outlet head 98 and squeezes the semi-circular sleeve 90 outward. The semi-circular sleeve 90 initially blocks the discharge hole 99, but as the semi-circular sleeve 90 moves outward, the hydrochloric acid solution inside the first feed pipe 62 enters the hydrochloric acid tank 2 through the discharge hole 99. By extending the outlet of the filling pipe to the bottom of the tank and using a bent pipe and a multi-hole nozzle, the hydrochloric acid flows horizontally out of the bottom of the tank, rather than vertically impacting the liquid surface. Vertical impact would create violent turbulence and waves, thus avoiding the turbulence caused by the filling of hydrochloric acid solution and the impact force on the inner wall of the tank, which would indirectly cause shaking. At the same time, it avoids filling from a high drop and reduces the impact force caused by the drop.

[0043] In use, the invention works as follows: First, the servo motor 4 is started, causing the lead screw 5, connected to its output end via a coupling, to rotate forward. The internally threaded sliding plate 61, threaded onto the outside of the lead screw 5, carries the first feed pipe 62 towards the hydrochloric acid tank 2. The other end of the first feed pipe 62 is then inserted into the hydrochloric acid tank 2, and subsequently, the first feed pipe 62 extends sequentially into the hydrochloric acid tank 2 and the casing channel 71. During its insertion, the first feed pipe 62 is stopped by the center plate 72 and then bends forward along the casing channel 71. Simultaneously, the first guardrail 73 and the second guardrail 74, welded to the casing channel 71, limit the movement of the first feed pipe 62. Finally, the first feed pipe 62 enters the inner pipe 91 and squeezes the connecting rod plate 96 inward. The straight rod 97, connected to the other side of the connecting rod plate 96, passes through the discharge hole 99 outside the liquid outlet head 98 and squeezes the semi-circular sleeve 90 outward. The semi-circular sleeve 90 initially blocks the discharge hole 99, but as the semi-circular sleeve 90 moves outward, the hydrochloric acid solution inside the first feed pipe 62 enters the hydrochloric acid tank 2 through the discharge hole 99. This operation belongs to the first gradient, that is, the process of the semi-circular sleeve 90 being pushed outward by the straight rod 97. During this process, the connecting rod plate 96 moves inward along the inner wall of the inner pipe 91 and squeezes the telescopic plate 95, causing the telescopic plate 95 to contract, but it does not push the baffle plate 94.

[0044] As the hydrochloric acid solution accumulates inside the hydrochloric acid tank 2, when the solution reaches half its height, it provides buoyancy to the first floating plate 23, causing it to move upwards along the vertical groove 22. Simultaneously, the indicator rod 24 welded to the top of the first floating plate 23 extends outwards from the top of the hydrochloric acid tank 2, providing the operator with guidance for the next step. When the indicator rod 24 extends upwards from inside the hydrochloric acid tank 2, the servo motor 4 is restarted. The start and stop of the servo motor 4 are divided into two stages. The first stage involves the folded tube 67 extending into the second feed pipe 81 without actually folding, coinciding with the flow of hydrochloric acid from the outlet 99. The second stage involves the first feed pipe 62 penetrating deeper into the inner pipe 91, while the folded tube 67 is compressed. In addition, the second stage of the start and stop of the servo motor 4 is when the hydrochloric acid solution accumulates to half the height of the hydrochloric acid tank 2. At this time, the hydrochloric acid solution will cause the second floating plate 82 to move upward, and the top insertion rod 83 connected to the top of the second floating plate 82 will move upward together with the sealing plate 84 connected to it by the triangular plate. The sealing plate 84 initially seals the outlet of the second feed pipe 81. As the sealing plate 84 moves upward, some of the hydrochloric acid inside the first feed pipe 62 will enter the second feed pipe 81 through the inclined sleeve 63, the connecting pipe 64, the arc pipe 65 and the folded pipe 67 in sequence, and finally be discharged into the hydrochloric acid tank 2.

[0045] The feed pipe 62 goes deeper into the inner pipe 91 and squeezes the connecting rod plate 96 a second time. At this time, the telescopic insert 95, which is in a contracted state, squeezes the baffle plate 94, causing the tough baffle plate 94 to be housed in the protective frame 93. Meanwhile, the hydrochloric acid solution inside the inner pipe 91 is discharged outward from the square hole 92.

[0046] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. The numbers one and two are not limited in quantity or model. The above positional limitations are based on the accompanying drawings. In actual settings, adjustments can be made according to actual needs. All modifications made by those skilled in the art based on the above concept without creative effort fall within the scope of protection of the present invention.
